Before answering your question I will demonstrate my pedantry by stating                        
that "one way crypt" is actually not encryption at all: it is "hashing".                        
Using a popular hashing algorithm is best, so I would also recommend                            
MD5; the only other serious contender would be SHA.                                             
I prefer encoding the hash in base64 rather than hex since the resulting                        
string is shorter.                                                                              
What are you planning to use this for?
